| Objective: | |||
| An enthusiastic Black Belt comes to you and states that next Friday morning at 10:15 AM the Project Champion is going to collect 20 temperature measurements inside one of the new Suntouch conveyor ovens at Store 243 to see if these ovens perform the same as the older model currently in use at other stores. She says, "We will be running Minitab to crunch the numbers." You say to her, "Before you do this, I have some questions to ask you about your strategy for this study." She tells you that she only has a few minutes before a meeting with the Champion to discuss the data collection, so you need to make your questions count! | |||
| Instructions for you: | |||
| (1) List 10 questions that you think are the most important questions to ask to ensure that your Black Belt has a good stragegy in place for this study and has addressed all important issues. Provide a brief (less than 15 word) rationale for each question. NOTE: Follow-up questions for clarification do NOT count as separate questions. (2) Identify 5 tools that could be used to help answer the question posed by your Black Belt in this study. Justify your choice of each tool in 15 words or less. | |||

| Question 1 | What is the range of temperatures? | ||
| To gauge the min and max values of temp recorded within the new oven. | |||
| Question 2 | What is the variability of the temperatures? | ||
| How often do the temperatures vary within the range. | |||
| Question 3 | What are the potential failure mode? | ||
| Some of the modes the through which the new oven can fail. | |||
| Question 4 | What are the effects of the potential failure? | ||
| The effects to the organisation of having the oven failuring. | |||
| Question 5 | What is the likely severity effect of a failure of the new oven? | ||
| The severity effect of a failure of the new oven. | |||
| Question 6 | What are some of the potential causes of the failure? | ||
| Examines some of the potential causes of a failure of the new oven. | |||
| Question 7 | What is the probability of a failure of a new oven? | ||
| Examines the likelihood of a failure of the new oven. | |||
| Question 8 | What is the probability of detection of a failure/temp going beyond the range? | ||
| Examines the probability of detection of a failure or temperatures going beyond normal range. | |||
| Question 9 | What is the probability of detection in time? | ||
| Examines the likelihood of detection and correction before the failure becomes severe. | |||
| Question 10 | What are some of the control systems in place? | ||
| Examines the number of control systems put in place to detect and correct a failure. | |||
| List five tools your Black Belt might use to answer her question in this study | Temperature recordings | and why? | Recordings would be useful in assessing temp range and variability. |
| and give a brief (10 words | Manual Instructions | and why? | Would be useful in evaluating the control systems. |
| or less) explanation of why each tool would be useful in this particular study. HINT: Each tool listed must be appropriate for THIS particular study. Do NOT go beyond the scope of the question being investigated by your Black Belt! | |||
| Workers' views and opinions | and why? | Would be useful in assessing the causes of failure and its probability. | |
| Supervisors' reports | and why? | Would be very critical in analysing the probability of failure and control systems. | |
| Own observations | and why? | Very crucial in proving a true and fair opinion and comparing with the failure reports and control systems reports. | |
